Ive never had a problem with any head ive ever used (well, some mechanicals had issues with penetration). Ive used all kinds of heads, 1970s bear file edge, went from there to thunder heads back in the 80s and shot those up until the mid 90s. Since then ive used sonics, liberty, slick tricks, monotec, magnus, Eagles, and several different mechanicals. Lost interest in the mechanicals. Ill be using Magnus and monotec with my trad bows and if I pull out the compound this year, it will be Muzzy. The key is to have your gear tuned. If your arrow, head, and bow are all tuned, you shouldnt be seeing much planning at normal distances with most any head now a days.
